The industrial activity development is based on a complete of material systems developed by the Engineer. In particular, the installation security require not only a perfect knowledge of components, but also a detailed analysis of the global response of these systems under various loading, in order to predict physics and mechanics phenomena that are likely to occur.
These phenomena can be static, repeated, variable, dynamic or delayed. Analysis methods and approaches of these actual issues of material and structure mechanics are the topic of this option.
Topics
- new materials (composites, shape-memory alloy, micro or nanostructured materials) but also more traditional materials in constant evolution (metal and alloys, polymers, timber, ceramics, glass). Designing, development, characterization and prediction of the in use and ultimate properties, analysis of the relations between behavior and microstructures, optimization;
- the anelastic response of materials and structures under mechanic and thermal load;
- fracture mechanics: brittle or ductile frature. Security of overload fracture. Calculation of the lifetime of structural fatigue;
- problems of stability and bifurcation met in the solid studies: of elastic and elasto-plastic solids, spreading stability of the cracking systems in brittle fracture;
- digital engineering methods: methods of finite elements: principe and practice in conjunction with industrial calculation codes, methods of integrale equations;
- smart materials, that changing their shape depending of magnetic or external electric fields;
- architectured materials;
- machine learning for material design.
Internships
Internship subjects from actual studies in the evolving technological fields like aeronautics and space, offshore, nuclear engineering, geophysics, industrial engineering, comuter-aided engineering, are offered to students in various industrial and academic laboratories of the Paris region, provinces and abroad.
Students interested in this option will have to send the whish page (available on the catalogue site - educational ressources) to the teacher in charge of the option. This page must specify the chosen internships among the proposed ones by the option, the list will be available online on the same site in October, and will be regularly updated, or the ones found by the students, and that will need to be validated by the teachers in charge of the option. Students will always have the possibility to contact one of the teachers, to define the best internship for the student
